Thule T2 Reverse Loading

Anyone tried to load bikes the other way around on the Thule T2? By this I mean clamping the bike down by the rear wheel instead of the front to get away with the problem of the fork hitting the clamp, specially on DH bikes. An obvious down side is the front tire might turn and stress the wheel clamp but unless something hits the bars, I don't think it's going anywhere. Or purchasing another wheel lock and using both on one wheel could secure the front tire better. Any thoughts?
